rl`his invention relates to insect powder distributors, and has for oneof its objects the provision of a novel and simple device of thischaracter through the medium of which the powderl may be easilydistributed in an efficient and economical manner.

A further object of the invention is the provision of an insect powderdistributor which shall include a flexible air chest and powderreceptacles secured to the ends of and communicating with the air chestand provided with discharge ports, the device being adapted' to be usedto distribute the powder in one receptacle first and thereafter todistribute the powder in the other receptacle, and adapted to beoperated by alternately moving the receptacles toward and away from eachother.

With the. foregoing and other objects in view, the invention consists inthe novel construction, combination. and arrangement of partshereinafter fully described and claimed, and illustrated in theaccompanying drawing, wherein:

Figure l is a view in side elevation of a powder distributor constructedin accordance with my invention,

Figure 2 is a sectional view taken on a plane extending longitudinallyand centrally through the powder distributor, and

Figure 3 is a sectional view taken on the plane indicated by the line3-3 of Figure 2.

Corresponding and like parts are referred to in the followingdescription, and designated in the several views of the accompanyingdrawing. by similar reference characters.

rthe powder distributor comprises a ilexible air chest l and powderreceptacles 2. These parts are preferably cylindrical, and the air chestl may be made of paper, cloth, leather or other suitable material. .Thereceptacles 2 are preferably made of metal, and are positioned in theends of the air chest l. The ends of the air chest l may be secured tothe receptacles 2 by an adhesive or in any other suitable manner. Theinner end walls 3 of the receptacles 2 are perforated as shown at 4, andthe outer ends of the receptacles are closed by caps 5 which are securedin place by the ends of the air chest l and provided with axiallyarranged discharge ports 6. Removable closures 7 are provided for thedischarge ports 6 and comprise stems S which pass through the ports andheads 9 which overlie the ports andV contact with the outer sides of thecaps 5.

lVhen it is desired to distribute the powder of one of the receptacles2, the closure 7 of the receptacle is removed. rlhe receptacles 2 arethen grasped and alternately moved toward and away from each other.lVhile the reeptacles 2 are being moved in the direction of each other,the air in the chest l is forced into the receptacle from which theclosure has been removed, the air passing into the receptacle throughthe openings et and forcing` the powder therefrom through the dischargeport 6. As the inner end walls 3 of the receptacles 2 are perforated,the air will enter the receptacle, from which the closure has beenremoved, in fine streams, and will as the result break up the powder tosuch degree of fineness as to permit of its passing freely through theuncovered discharge port 6. While the receptacles 2 are being moved awayfrom each other, air flows into the chest l by way of the openeddischarge portsG and openings 4. After all of tl e powder of thisreceptacle has been distributed, the closure 7 of this receptacle isreapplied, and the closure 7 of the other receptacle removed. The powderof this other receptacle may new be distributed by grasping bothreceptacles and alternately moving them toward and away from caca other.

From the foregoing description7 taken in connection with theaccompanying drawing, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains. Ylfhile l have described theprinciple of operation of the invention, together with the device whichI now consider to be the best embodiment thereof, l desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of theinvention as claimed.

lVhat is claimed is A A powder distributor comprising a. :tleXi-' bleair chest of tubular formation, a relatively long receptacle telescopedfor substantially its length in an end of the air chest and having itsinner end Wall perforated, a cap telescoped over the outer end of thereceptacle and overlapped and secured in place by the adj acont endportion of the air chest, said cap having a, discharge port.

In testimony whereof I affix my signature.
